Virtual Interfaces

addresses assigned to it, e.g. as with a port provided by an an Internet Service
Provider.
Figure 48: Creating a Virtual Interface
The only new parameter is the virtual interface descriptor, which must be a numeric
value. As an example a virtual interface numbered 0 on eth1 appears as eth1:0 in
interface descriptions and routing tables.
Virtual Lan Interfaces
Click the link “Add Virtual Lan Interface” when you want to create a VLAN interface.
Figure 49: Creating a Virtual Lan Interface
The only new parameter is the vlan id, which must be a numeric value between 1 and
4094. The vlan id will be changed automatically as 4 digits (prefixed with 0) if the
input is less than 4 digits. For example, if the input is 2, it will be automatically
changed to 0002.
